Summary:                    Python "import RDF" gives "The process has forked
and you cannot use this CoreFoundation functionality safely. You MUST exec()"
Description: 
I have a Python web-server application, built with web.py, that uses librdf. All
works well running directly under Python. However, attempting to run the
application under Apache/2.2.17 with mod_wsgi/3.3 and Python/2.7.1 results in
"The process has forked and you cannot use this CoreFoundation functionality
safely. You MUST exec()." errors. 

What might be being forked, presumably as part of librdf's initialisation? I
have configured librdf so only the memory triple store is enabled, trying to
eliminate backend database code.

Any and all clues appreciated!!

Steps to Reproduce: 
The following trivial mod_wsgi and web.py example works just fine until the
"import RDF" line is enabled. Apache's log file then has three lines of the
above error.


##############

import web
#import RDF  ## Error if RDF imported

urls = ( '/.*', 'hello', )

class hello:
    def GET(self):
        return "Hello, world."

application = web.application(urls, globals()).wsgifunc()
